I picked up my 2013 GT last week and I'm doing some research on different exhaust set ups. Im leaning towards the Roush axel backs but I'm not 100% sure yet. From the youtube vids I've watched, i can say the Roush seem to sound the best IMO. Im looking to avoid drone and i would like to know if anyone has the Roush with 3.73s and if there is drone at any RPM? From what i hear, if there was drone, it would be most noticeable around 2000 RPM's and with the 3.73s, at most cruising speeds around town and highway, i seem to be right around the 2000 RPM range. Thanks

I live in Michigan. But my girl (12' GT ) has never seen snow/salt. And rain only once. The rust comes from inside/condensation. I've heard that Roush will stand behind their product. But I just found it and haven't done anything about it YET.
